SPRINKLING-CAR FOR MINES.

Application filed January 26, 1908.

T 0 all whom it may concern:

Be it known that we, PETER DONEY and ALEXANDER P. Cocnnann, citizens of the United States of America, residing at Monongahela city, in the county of \Vashington and State of Pennsylvania, have invented certain new and useful Improvements in sprinkling-Cars for Mines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to sprinkling cars for mines, and the primary object of our invention is, to provide a novel sprinkling car or water tank that can be moved back and forth in a mine, to allay dust therein, such as coal dust.

Another object of our invention is to provide a novel sprinkling car wherein positive and reliable means are employed for sprinkling or spreading water upon the bottom, sides and roof of a mine. To this end, we aim to provide a sim le and inexpensive sprinkling car that will be highly efficient for allaying and reducing to a solid form such coal dust that may accumulate in a mine. By our sprinkling car we also solidity certain gases, and with other gases the water sprin kled by our car has a tendency to drive the same from the mine.

The detail construction entering into our invention will be presently described and then specifically pointed out in the appended claim.

In the drawings: Figure 1 is an elevation of our car partly in section, Fig. 2 is a plan of the same, Fig. 3 is a detail perspective view of a pipe connection, and Fig. 4 is a detail view of a perforated pipe used in connection with the car.

To put our in\ ention into practice, we provide trucks 1 and 2, the axle of truck 2 being provided with a sprocket wheel I at one side of the car, for driving a pump, carried by the car.

The body of the car is substantially rec tangular and. comprises a closed tank 4 that is filled through the medium of an opening 5 formed in the top of the tank.

Upon the tank, adjacent one end thereof are arranged bearings 6 for a crank shaft 7, this shaft having a sprocket wheel 8 over which an endless sprocket chain 9 travels, this chain engaging the sprocket wheel 3 of the truck 2.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Serial No. 412,656.

Detachably connected to the crank shaft 7 by a pin 10 is a pitman 11, said pitman connecting with the iston rod 12 of a pump 13, said pump being ocated centrally on the top of the tank 4.

Extending downwardly into the tank 4 from one side of the pump is an inlet pipe 14, and extending to the end of the tank from said pump is an outlet pipe 15. The outlet ipe 15 is connected to a U-shaped tubular raine 16, which is secured to the tank 4 by stra s 17. This U-shaped frame 16 is preferab y constructed of pieces of pipe, and is provided with laterally extending erforated pipe sections 18. The top of the rame 16 is also perforated, whereby water will be projected against the roof of a mine, while the perforated pipe sections 18 will project water against the sides and floor of the mine.

It is thought that from the foregoing description taken in connection. with the drawings, the operation of the sprinkling car will be fully understood, and we reserve the right to make such structural changes as fall within the scope of the invention claimed.

Having now described our invention what we claim as new, isr' A sprinkling car of the type described comprising a tank and wheeled trucks supporting the same, a pump carried on the top of the car, a gearing connecting the pump with the axle of one of the trucks, combined with a substantially U-shapcd sprinkler frame embodying a perforated pipe extending across the top of the tank am in communication with the tank through the pump, vertical pipes communicating at their upper ends with said top pipe, perforated branch pipes projecting longitudinally from both ends of said vertical pipes, the said top pipe l'iaving its perforations directed to project the water upwardly and. the said longitiulinally extending branch pipes ha wing their perforations directed to project the water both laterally and downwardly.

In testimony whereof we aliix our signatures in the presence of two witnesses.
